Events and promotions signage have temporary purposes, but need to be clear and effective communication of your message. Here is an example:

This project done a while back, in 2000 - Etnies came to our company with their need to put large temporary graphics on their project at the LA County Fair. They had a pop-up store and a pretty nice skateboard park, which needed their logo graphics painted on. The yellow banding around the store was painted on at the same time… pretty eye-catching results!

Of course, with use, unless the paint used on the skate ramps was very tough, the park would not look attractive. I solved that problem by using a 2-part urethane paint.
